For the best accommodation near surf, stay on the South Coast of Upolu. All the best waves are centered around Sinalei Reef Resort, Coconuts Beach Club Resort and there is also a good basic style beach fale accommodation called SIna PJ's. There is a surf transfer outdoor adventure company based at/keeps their boats at Cocontus Beach Club but services all the resorts on the South Coast (picks you up from Sina PJ's) for surf transfers to all the spots on the south coast there called Manoa Tours check them out on Trip Advisor.
